Patent DE-4141158-A1 (DE)
Inventor: SCHOLL RAINER DIPL ING
IPC: A61G5/14
Filed: 1991-12-13
Abstract: A wheelchair may be if necessary equipped with a standing up device that has two spars (1) vertically arranged during use, linked to the wheelchair (13) and provided with means for converting a manual or mechanical force that lifts the user into a lifting force that acts upon the body of the user by means of holding means and at least a lifting cable (2) linked thereto, whereas the device may be secured in the standing position of the user. When the device is used as an aid that allows the user to stand up, at least two deflection rollers (3, 4) are used as converting means on each of the spars (1) that can be removed from the wheelchair. One of the deflection rollers (3) converts the lifting force that acts on the body of the user over a seating band (7) designed as a holding means into a forwardly and upwardly directed force that aids the user to stand up, so that it is possible to equip any wheelchair with a standing up device that imitates by simple means the natural standing up movement.

Title: Complementary MOS to emitter-coupled logic level converter - gives output voltages from three-stage bipolar level-shifter referred to fixed potential
Inventor: BARRE CLAUDE DIPL ING
IPC: H03K19/0175
Filed: 1992-05-06
Abstract: A current-switching stage (1) in the emitter circuit of a bipolar transistor (4) drives a level-shifting stage (2) contg. the base-to-emitter paths of cascaded bipolar transistors (13-15). The base of the first transistor (4) is returned to a fixed reference voltage (V1) which exceeds the emitter supply voltage (VCC) by four times the drop across a diode. The high CMOS level of input (5) causes an n-channel MOSFET (11) to shunt the resistance-diode combination (10,12). The low CMOS level cuts-off the MOSFET so that the resistance (10) drops about 0.8 V to the ECL signal level. ADVANTAGE - Function of following emitter-coupled logic stages is not jeopardised by relatively small fluctuations of supply voltage.

Title: Hydraulically working servo linkage with pressure limiting valve - limits pump pressure and power when servo motor blockaded until pressure medium feed to damaged work chamber is interrupted
Inventor: RUEFFER MANFRED DIPL ING
IPC: B62D5/06
Filed: 1993-02-04
Abstract: The throughput resistances (A1,A2) of the valve has a large hysteresis dependent upon the pressure in the pressure conduit (11). Under a first high pressure, the valve leaves its closure position and springs to an open position. It returns to its closure position at a closure pressure which is much less than the opening pressure. The opening pressure is 200 bars and the closure pressure is 3 bars. The valve maintains its opening pressure until the pressure drops to 40 bars. The opening surface of the valve body (1) effective in the opening direction in the closure position of the valve is very much smaller than a second opening surface effective in the opening position of the valve. ADVANTAGE - Independent of the link position in the event of a blocking cuts out the linkage aid and thereby reduces the pump power until a new link aid requirement is established.
